  Conventionally, a track traveling toy including a track formed endlessly and a traveling body that floats on the track and travels along the track is known (see, for example, Patent Document 1). In this track traveling toy, a permanent magnet is disposed on the bottom wall of the track and a permanent magnet is disposed on the bottom surface of the traveling body, and the traveling body is levitated on the track by repulsion of magnetic force. Further, in this track toy, an electromagnet is disposed on the side wall of the track and a permanent magnet is disposed on the side surface of the traveling body, and the electromagnet is energized each time the traveling body passes in the vicinity of the electromagnet. A magnetic force is generated between the side surface of the traveling body and a driving force for traveling is applied to the traveling body.

No. 7-27989

However, the track traveling toy described in Patent Document 1 has a problem that it is difficult to stably float a traveling body traveling along the track on the track.
The present invention has been made in view of these problems, and an object of the present invention is to provide a technique for stably levitation of a traveling body traveling along a track.

  In order to achieve the above object, the device according to claim 1, wherein the first rail incorporating the first magnet and the second rail incorporating the first magnet are spaced apart from the first rail by a predetermined distance. It arrange | positions between the 2nd rail arrange | positioned so that 1 rail may be opposed, and it arrange | positions so that an attraction | suction force may generate | occur | produce between a 1st magnet and a 2nd magnet. By incorporating the third magnet, the levitation traveling body for toy floats between the first rail and the second rail and travels along the first rail and the second rail, and the third magnet is disposed inside. A housing case, a third magnet housed in the housing case, and an elastic member that connects the housing case. The third magnet has a first toy levitation body in the housing case. For the direction of travel along the rail and the second rail Characterized in that it is installed movably along a vertical direction.

  The toy levitating body configured as described above is generated between the first magnet and the third magnet disposed between the first magnet and the second magnet disposed so as to face each other. It floats by the balance between the attractive force and the attractive force generated between the second magnet. And since the accommodation case and 3rd magnet which accommodate a 3rd magnet are connected by the elastic member, an accommodation case also floats when a 3rd magnet floats.

  Furthermore, the third magnet is installed in the housing case so as to be movable along a direction perpendicular to the traveling direction in which the toy floating traveling body travels along the first rail and the second rail. Since it is the elastic member that connects the housing case and the third magnet, the vibration of the housing case is hardly transmitted to the third magnet. This is because the vibration energy of the housing case is absorbed by the elastic member. Thereby, even if it is a case where an external force works on the floating storage case and the storage case vibrates, in the 3rd magnet, between the attractive force generated between the 1st magnet and the 2nd magnet It becomes easy to maintain a position where the generated suction force is balanced, and the toy levitating body can be stably levitated between the first rail and the second rail.

  Further, when a propulsive force for running the toy levitating body between the first rail and the second rail is applied by a magnetic force generated between the third magnet and the electromagnet, this magnetic force is an external force. As a result, the third magnet may vibrate by acting on the third magnet. However, since it is the elastic member that connects the housing case and the third magnet, vibration generated by the third magnet is hardly transmitted to the housing case. For this reason, even when the third magnet vibrates, this vibration is suppressed from being transmitted to the housing case, and the toy levitating body is stably levitated between the first rail and the second rail. Can be made.

  The invention according to claim 2 is a track traveling toy comprising the toy floating traveling body according to claim 1 and a traveling toy track having the first rail and the second rail according to claim 1. And a 1st rail and a 2nd rail have a curve part formed in the shape of a curve so that advancing direction may change as a levitating traveling body for toys moves along the 1st rail and the 2nd rail.

  When the toy levitating traveling body of the orbital traveling toy configured in this way is traveling on the curved portion, the rail on the inner peripheral side of the curved portion of the first rail and the second rail and the third magnet The distance between the first rail and the second rail is shorter than the distance between the rail on the outer peripheral side of the curved portion and the third magnet.

  For this reason, the first magnet and the second magnet in the curved portion are the same as the straight portion that is linearly formed so that the traveling direction does not change as the toy floating traveling body moves along the first rail and the second rail. When the magnets are arranged in the first rail and the second rail, the third magnet can maintain a balance between the attractive force generated between the first magnet and the attractive force generated between the second magnet. Disappear.

  In view of this, the invention according to claim 2 is that the first magnet and the second magnet of the curved portion are respectively the first magnet and the third magnet when the toy levitating body is moving along the curved portion. It is characterized by being arranged in the first rail and the second rail of the curved portion so that the distance between the first magnet and the second magnet is equal to the distance between the second magnet and the third magnet.

  The track toy configured as described above maintains a balance between the attractive force generated between the first magnet and the attractive force generated between the second magnet and the third magnet even in the curved portion. can do. For this reason, even if the toy levitating body travels on the curved portion, the toy levitating body can be stably levitated between the first rail and the second rail.

Embodiments of the present invention will be described below with reference to the drawings.
[Configuration of the orbital traveling toy 1]
FIG. 1A is a front view showing the configuration of the track traveling toy 1. FIG. 1B is a plan view showing the configuration of the carriage 12.

  As shown in FIG. 1A, the track traveling toy 1 includes a model train 10, a track 20 that forms a travel route for the model train 10 to travel, and a drive for the model train 10 to travel. The drive part 30 which generates force is provided.

The model railway vehicle 10 includes a vehicle main body 11 made to imitate the appearance of a real railway vehicle, and a carriage 12 on which the vehicle main body 11 is placed.
As shown in FIGS. 1A and 1B, the carriage 12 is installed between a rectangular parallelepiped housing case 121, a magnet 122 housed in the housing case 121, and the housing case 121 and the magnet 122. Spring 123 and guide wheels 124 installed on both side surfaces of the housing case 121.

  The magnet 122 is formed in a rectangular parallelepiped shape (see FIG. 3A), and is accommodated in the accommodation case 121 so that the top surface is an N pole and the bottom surface is an S pole. Hereinafter, the magnet 122 is referred to as a levitation magnet 122.

One end of the spring 123 is attached to the top plate constituting the top surface of the rectangular parallelepiped housing case 121, and the other end is attached to the top surface of the magnet 122.
A bar-like member 125 and a bar-like member 126 are provided on the top and bottom surfaces of the levitation magnet 122, respectively, extending in the vertical direction from the top and bottom surfaces. Further, through holes 121a and 121b are formed in the top surface and the bottom surface of the housing case 121 that houses the levitation magnet 122, respectively. The rod-shaped member 125 and the rod-shaped member 126 are inserted into the through hole 121a and the through hole 121b, respectively. Accordingly, the levitation magnet 122 connected to the housing case 121 via the spring 123 can move in the up-down direction in the housing case 121.

  The guide wheels 124 are installed on the front side and the rear side in the traveling direction on each of both side surfaces of the storage case 121, and perpendicular to the top surface (or bottom surface) of the storage case 121 along both side surfaces of the storage case 121. It is attached so as to be rotatable around a provided rotation shaft 127. That is, the guide wheel 124 is attached in a state where half of the guide wheel 124 protrudes from both side surfaces of the housing case 121. Further, in order to reduce the frictional resistance by reducing the contact surface with the track 20, the guide wheel 124 is formed so that its circumferential surface (thickness direction) is a semicircular curved surface having the wheel thickness as a diameter. ing.

  As shown in FIG. 1A, the track 20 has a pair of rails 21 and 22 arranged so as to face each other, and the rails 21 and 22 are positioned above the surface PI on which the track 20 is installed. Track fixing bridges 23 and 24 for supporting 21 and 22, respectively.

  The rail 21 includes a magnet 211 and a storage case 212 that stores the magnet. The rail 22 includes a magnet 221 and a storage case 222 that stores the magnet.

  The magnets 211 and 221 are formed in a rectangular parallelepiped shape, and are housed in the housing cases 212 and 222 so that the top surface side is the S pole and the bottom surface side is the N pole. Hereinafter, the magnets 211 and 221 are referred to as orbital magnets 211 and 221, respectively.

  The housing cases 212 and 222 are formed of a low friction material in order to reduce the frictional resistance with the guide wheels 124. In addition, the storage cases 212 and 222 take into account the possibility that the top surface of the track magnets 211 and 221 and the top surface of the levitation magnet 122 may deviate from the same plane due to the weight of the model train vehicle 10 (sinking). The vertical lengths 212 and 222 are given a margin.

  As shown in FIG. 2, the rail 21 includes two straight portions 21a and 21b formed in a straight line, and two curved portions 21c and 21d formed in a semicircular shape. It is formed in an endless shape by connecting both end portions of the straight portion 21b with curved portions 21c and 21d, respectively.

  The rail 22 includes two straight portions 22a and 22b formed in a straight line and two curved portions 22c and 22d formed in a semicircle, and both ends of the straight portion 22a and the straight portion 22b. Are connected to each other by curved portions 22c and 22d, and are formed endlessly, and are arranged on the inner peripheral side of the rail 21.

The drive unit 30 includes an electromagnet 31, a light / dark sensor 32, a light source 33 (see FIG. 1A), a power supply 34, and a control circuit 35.
One or a plurality of electromagnets 31 (six in this embodiment) are installed along the track 20 between the rails 21 and 22 and below the rails 21 and 22 (see FIG. 1A). Is done.

  The light / dark sensor 32 has a lower resistance value as the illuminance of incident light increases, and senses an increase or decrease in illuminance based on this resistance value. The light / dark sensor 32 is disposed between the rail 21 and the rail 22 and below the rails 21 and 22 in the vicinity of each electromagnet 31 (see FIG. 1A).

The light source 33 is disposed above the rails 21 and 22 so as to face the light / dark sensor 32 (see FIG. 1A).
The power source 34 includes a first power source 341 that supplies current to the light / dark sensor 32, the light source 33, and the control circuit 35, and a second power source 342 that supplies current to the electromagnet 31.

The control circuit 35 controls energization to the electromagnet 31 based on the detection result of the light / dark sensor 32.
[Left principle of model train 10]
As shown in FIG. 1A, when the carriage 12 is disposed between the rail 21 and the rail 22, N is a magnetic pole on the top surface side of the levitation magnet 122, as shown in FIG. The pole and the S pole that is the magnetic pole on the top surface side of the orbital magnets 211 and 221 are opposed to each other, and the S pole that is the magnetic pole on the bottom surface side of the levitation magnet 122 and the bottom side of the orbital magnets 211 and 221 The N pole, which is a magnetic pole, can be opposed. Accordingly, an attractive force AF1 is generated between the levitation magnet 122 and the track magnet 211, and an attractive force AF2 is generated between the levitation magnet 122 and the track magnet 221. If the carriage 12 is arranged so that the distance between the levitation magnet 122 and the track magnet 211 and the distance between the levitation magnet 122 and the track magnet 221 are equal, the suction force AF1 and the suction force The force AF2 is balanced, whereby the model railway vehicle 10 is kept in a state where it floats between the rail 21 and the rail 22.

[Vehicle stability]
The magnetic force is inversely proportional to the square of the distance between the magnets, and the magnetic force becomes weaker as the distance between the magnets increases. In order to realize the stability of the model railway vehicle 10 against external force and the smooth running of the model railway vehicle 10, the track magnets 211 and 221 are fixed to the rails 21 and 22, and the magnetic force becomes unstable due to the change in distance. It is necessary to maintain an appropriate distance so as to suppress the fall and drop off of the railway model vehicle 10 from the track 20.

  For this purpose, guide wheels 124 are arranged on both side surfaces of the levitation magnet 122. 4 (a) and 4 (b), the carriage 12 of the model train vehicle 10 is moved between the linear rail 21 and the linear rail 22 by the guide wheels 124. It is possible to maintain an optimum distance between the orbital magnets 211 and 221 and keep the attraction forces AF1 and AF2 constant. FIG. 4B shows a state when time has passed from FIG. 4A, and an arrow D1 in FIGS. 4A and 4B shows the traveling direction of the carriage 12. FIG. .

  Further, the carriage 12 includes a spring 123 that connects the housing case 121 and the levitation magnet 122. Therefore, as shown in FIGS. 5A and 5B, the levitation magnet 122 can move freely along the vertical direction without following the movement of the carriage 12 (see arrows AL1 and AL2). 5A is a side view showing the configuration of the model train vehicle 10, and FIG. 5B is a front view showing the configuration of the model train vehicle 10. As shown in FIG.

  As a result, as shown in FIG. 6A, the vibration of the traveling carriage 12 itself is less likely to be transmitted to the levitation magnet 122. FIG. 6A is a diagram showing a change in the position of the levitation magnet 122 when the model railway vehicle 10 moves downward. For this reason, the height of the levitation magnet 122 is maintained such that the levitation magnet 122 always faces the track magnets 211 and 221 regardless of the behavior of the trolley 12, and the trolley 12 can travel stably.

  Further, since the repulsive force (repulsive force) acting between the electromagnets 31 is less likely to be directly transmitted to the carriage 12, vibration of the carriage 12 can be suppressed and vibration can be accelerated as shown in FIG. It can be attenuated. FIG. 6B is a diagram showing a change in the position of the model train vehicle 10 when the levitation magnet 122 moves upward.

  When the levitation magnet 122 is fixed in the carriage 12, the balance of the magnetic force is disturbed because the carriage 12 and the levitation magnet 122 move together as shown in FIG. 7A. On the other hand, when the levitation magnet 122 is movable in the carriage 12, the levitation magnet 122 is stable regardless of the movement of the carriage 12, as shown in FIG. Is not disturbed.

  As described above, the train model vehicle 10 can travel on the track 20 smoothly and at a stable speed by the guide wheel 124 and the mechanism that connects the housing case 121 and the levitation magnet 122 by the spring 123.

  Further, the vertical behavior of the traveling carriage 12 is attenuated by the buffering action of the spring 123, so that it is difficult to be transmitted to the levitation magnet 122. Furthermore, even if the levitation magnet 122 moves upward due to repulsive force (repulsive force) acting with the electromagnet 31, the upward force directly transmitted to the carriage 12 is attenuated by the buffering action of the spring 123.

  Further, as shown in FIG. 8, repulsive force (repulsive force) generated between the levitation magnet 122 and the electromagnet 31 when the cart 12 and the levitation magnet 122 that travel horizontally on the track 20 pass directly above the electromagnet 31. RF1 generates a force that pushes the carriage 12 and the levitation magnet 122 held on the track 20 in the vertical direction by the attractive force between the levitation magnet 122 and the track magnets 211 and 221. The cart 12 itself having the levitation magnet 122 also receives this force. For this reason, when repulsive force (repulsive force) RF1 acts on the rear part of the carriage 12, the carriage 12 is slightly inclined downward. Subsequently, the inclined carriage 12 tries to return to the horizontal position by the attractive forces AF1 and AF2 between the levitation magnet 122 and the track magnets 211 and 221. Thereby, the carriage 12 vibrates in the vertical direction on the track 20. As shown in FIG. 8A, if the levitation magnet 122 is fixed to the carriage 12, the repulsive force (repulsive force) RF <b> 1 is easily transmitted to the carriage 12, and the vibration of the carriage 12 is easily continued. On the other hand, as shown in FIG. 8 (b), if the magnet can move freely in the vertical direction, the vibration of the levitation magnet 122 is less likely to be transmitted to the carriage 12 due to the buffering action of the spring 123. The twelve vibrations decay quickly.

[Arrangement of magnets for orbit]
The distance between the track magnets 211 and 221 and the levitation magnet 122 is always kept equal regardless of the straight portions 21a, 21b, 22a, 22b and the curved portions 21c, 21d, 22c, 22d of the rails 21, 22. It is desirable. When the distance between the orbital magnets 211 and 221 and the levitation magnet 122 is different between the right side and the left side of the levitation magnet 122, the attraction force with the shorter distance between the magnets becomes stronger, and the levitation magnet 122 is attracted. The magnetic force is different on the left and right, and the magnetic force becomes imbalanced. In this case, smooth running in the model railway vehicle 10 is hindered.

  As shown in FIG. 9A, this problem is unlikely to occur in a linear track (see arrows AL3 and AL4), but in a curved track, the distance between the track magnet outside the curve and the levitation magnet 122 is large. (See arrow AL5) and the gap between the track magnet on the inside of the curve and the levitation magnet 122 (see arrow AL6) are different (because there are guide wheels 124, they are narrow on the inside and wide on the outside), Considering this point, it is necessary to arrange the orbital magnets 211 and 221. As shown in FIG. 9A, in the case of a track that simply holds only the left and right width of the carriage 12 and does not take into consideration the distance between the orbiting magnet and the levitation magnet 122, the carriage 12 is a magnet inside the orbit. This is because it is strongly sucked and cannot smoothly run on the curve.

  Therefore, in the track 20 of the present embodiment, as shown in FIG. 9B, the distance between the track magnet 211 and the levitation magnet 122, regardless of the straight and curved portions of the rails 21 and 22, and the track The track magnets 211 and 221 are disposed in the housing cases 212 and 222 of the rails 21 and 22 so that the distance between the magnet 221 and the levitation magnet 122 is equal (see arrows AL7, AL8, AL9, and AL10). . As a result, the carriage 12 is attracted with equal forces by the track magnets 211 and 221 both inside and outside the track 20, and the model railway vehicle 10 can smoothly travel the curve of the track 20.

[Promotion of cart by magnetic force]
The carriage 12 is held horizontally by a magnetic force between the left and right rails 21 and 22. In this state, the carriage 12 does not run by itself unless an external force is applied. For this reason, the electromagnet 31 is used for propulsion of the carriage 12.

  When there are two magnets on different planes, the two magnets repel each other when the two magnets are arranged so that the same poles face each other. Using this characteristic, the model railway vehicle 10 is propelled forward. However, the railway model vehicle 10 is not propelled simply by disposing the electromagnet 31 at an appropriate distance below the levitation magnet 122 for the following reason.

  For example, considering the case where the carriage 12 circulates in a closed circular track such as the track 20, the carriage 12 is separated from the levitation magnet 122 by an appropriate distance between the rail 21 and the rail 22 and below the rails 21 and 22. If the magnets are arranged along the track 20 at equal intervals, it seems that the model railway vehicle 10 can be sequentially propelled. However, the carriage 12 fixed to the track and traveling only in a specific direction on the track is temporarily 1 When propelling by repelling with the first magnet and trying to pass the next magnet, the levitation magnet 122 of the carriage 12 receives the repulsive force of the next magnet arranged below the front surface in the traveling direction, Even if it can pass, the speed is reduced or it stops before the magnet. Even if a sufficient initial speed is applied to the carriage 12, the repulsive force of the magnets is successively received in the traveling direction, so that the speed reduction is accumulated and eventually stops.

  In order to avoid such a phenomenon, an electromagnet is used as the propulsion magnet. The electromagnet 31 is a copper wire wound in an iron core several hundred times in a coil shape, and generates a magnetic force only when energized. Therefore, when the levitation magnet 122 passes over the electromagnet 31, it is energized at an appropriate timing. Then, the repulsive force can be used only for the propulsion of the model railway vehicle 10.

  First, as shown in FIG. 10A, when the electromagnet 31 is positioned in front of the levitation magnet 122, the electromagnet 31 repels the levitation magnet 122 (see the repulsion force RF11) and pushes back the carriage 12 backward. The cart 12 stops or runs backward (see arrow AL11).

  Next, as shown in FIG. 10B, when the levitation magnet 122 is positioned immediately above the electromagnet 31, the electromagnet 31 repels the levitation magnet 122 (see the repulsive force RF <b> 12) and pushes up the carriage 12. The force acts and the carriage 12 stops or slows down (see arrow AL12).

  Further, as shown in FIG. 10 (c), when the electromagnet 31 is positioned behind the levitation magnet 122, the electromagnet 31 repels the levitation magnet 122 (see the repulsive force RF13) and moves the carriage 12 forward. The pushing force works and the carriage 12 is propelled (see arrow AL13).

  That is, when an electromagnet is used, if the electromagnet 31 is not energized when the electromagnet 31 is positioned in front of the levitation magnet 122 and the levitation magnet 122 is positioned immediately above the electromagnet 31, the carriage 12 is Since it does not receive a repulsive force, it can pass over the electromagnet 31 without being decelerated. If the electromagnet 31 is energized for the first time when the electromagnet 31 is positioned behind the levitation magnet 122, the carriage 12 can receive only the force pushing it forward. If this is performed for each electromagnet 31 arranged on the track 20, the carriage 12 can continuously travel on the track 20 without decelerating.

  However, the material used for the electromagnet 31 includes a ferromagnet, and when the levitation magnet 122 is on the track and immediately above the electromagnet 31, the electromagnet 31 is not energized, that is, is magnetized. Even in the absence, the levitation magnet 122 attracts the ferromagnetic material. In this case, the levitation magnet 31 may come into contact with the electromagnet 31 that is superior in weight. For this reason, the distance between the levitation magnet 122 and the electromagnet 31 is maintained so that the levitation magnet 122 does not contact the electromagnet 31 in a stationary state in consideration of the sinking from the track plane due to the weight of the vehicle body. And

[Running control]
An electromagnet 31, a light / dark sensor 32, a light source 33, a power source 34, and a control circuit 35 are used to control the traveling of the carriage 12.

  The light / dark sensor 32 is disposed in front of the electromagnet 31 with respect to the traveling direction of the carriage 12. The distance from the tip of the carriage 12 to the center of the electromagnet 31 and the distance from the center of the electromagnet 31 to the light / dark sensor 32 are set to the electromagnet 31 at an optimum timing in consideration of the reaction time of the light / dark sensor 32 and the movement speed of the carriage 12. Set to energize.

In addition, a light source 33 with high illuminance and brightness that is clearly distinguished from ambient light is installed directly above the light and dark sensor 32 that has been subjected to light shielding processing, at a position that does not interfere with the traveling of the carriage 23.
The control circuit 35 includes a control IC 351, a sensitivity adjustment volume 352, a mode changeover switch 353, a relay switch 354, and a pilot lamp 355 (see FIG. 12).

The control IC 351 has a function of processing a signal from the light / dark sensor 32 and turning on / off the relay switch 354.
The sensitivity adjustment volume 352 has a function of adjusting the sensitivity of the light / dark sensor 32.

  The mode changeover switch 353 is a control mode of the control IC 351. When the light / dark sensor 32 senses a decrease (darkening) in illuminance, the light-and-dark sensor 32 senses an increase in light (lightening) in mode 1 that turns on the relay. Then, it has a function of selecting any one of mode 2 for turning on the relay. In the present embodiment, mode 1 is selected for the mode switch 353.

  The relay switch 354 is turned on when an ON command is input from the control IC 351. The electromagnet 31 is connected to the relay switch 354, and current is supplied to the electromagnet 31 when the relay switch 354 is turned on.

The pilot lamp 355 is an LED that lights up when the relay switch 354 is turned on.
Next, a procedure for causing the model railway vehicle 10 having only one carriage 12 to travel on the track 20 will be described using the flowchart of FIG.

  First, the railway model vehicle 10 is placed on the rails 21 and 22 so that the levitation magnet 122 is positioned just above and slightly behind the electromagnet 31 (S10). Then, the first power supply 341 is turned on (S20). Thereby, an electric current is supplied to the brightness sensor 32, the light source 33, and the control circuit 35 (S30). At this time, since the light from the light source 33 is blocked by the model railway vehicle 10 and does not reach the light / dark sensor 32, the relay is in an ON state. Next, the second power supply 342 is turned on (S40). As a result, the electromagnet 31 operates as a magnet and repels the levitation magnet 122, whereby the model railway vehicle 10 starts to travel (S50).

  Then, when the model railway vehicle 10 passes between the next light and dark sensor 32 arranged on the track 20 and the light source 33 (S60), the light from the light source 33 is blocked by the model railway vehicle 10 (S70). The brightness sensor 32 senses a decrease in illuminance (S80). As a result, a signal is sent to the control IC 351, the relay switch 354 is turned on (S90), a current flows through the electromagnet 31 connected to the relay output terminal (S100), and the electromagnet 31 becomes a magnet to generate magnetic force ( S110).

  Then, when the levitation magnet 122 is behind the electromagnet 31, the levitation magnet 122 and the electromagnet 31 repel each other (S120), and the railway model vehicle 10 is propelled by strongly pushing the carriage 12 forward (S130). ). After that, when all parts of the model train vehicle 10 pass between the light / dark sensor 32 and the light source 33 (S140), the light from the light source 33 reaches the light / dark sensor 32 (S150), and the light / dark sensor 32 has an illuminance. A rise is detected (S160), a signal is sent to the control IC 351, the relay switch 354 is turned off, the current to the electromagnet 31 is cut off, and the magnetic force disappears (S170). And the process of S60-S170 is performed with the set of the light-and-darkness sensors 32 and the electromagnets 31 for the number installed in the track | truck 20 which passes when the trolley | bogie 12 drive | works on the track | truck 20, and runs continuously. If the propulsion by the repulsion of the magnet is performed with good timing, the carriage 12 continues to circulate on the track 20 without decelerating.

  In addition, even if it is the model railcar 10 in which two or more carts 12 are connected by a coupler, the cart 12 can be run on the track 20 in the same manner as the model railcar 10 having only one cart. .

Next, a control method in the case where the model railway vehicle 10 in which two or more carriages 12 are connected by a coupler travels on the track 20 will be described.
First, as shown in FIG. 12, when the head of the first carriage 12a passes between the light and dark sensor 32 and the light source 33, the light and dark sensor 32 detects a decrease in illuminance. As a result, a signal is sent to the control IC 351, the relay switch 354 is turned on, a current flows through the electromagnet 31 connected to the relay output terminal, and the electromagnet 31 becomes a magnet to generate magnetic force.

  Then, the levitation magnet 122 and the electromagnet 31 repel each other when the levitation magnet 122 of the first trolley 12a is behind the electromagnet 31, and the first trolley 12a is strongly pushed forward. 10 promotes. Thereafter, as shown in FIG. 13, the first carriage 12 a passes between the light / dark sensor 32 and the light source 33. When all parts of the first carriage 12a pass between the light and dark sensor 32 and the light source 33, the light from the light source 33 reaches the light and dark sensor 32, so that the light and dark sensor 32 detects an increase in illuminance, A signal is sent to the control IC 351, the relay switch 354 is turned off, the current to the electromagnet 31 is cut off, and the magnetic force disappears.

  Thereafter, since the coupler 15 for connecting the first and second carts 12a and 12b is formed of a material having excellent light transmission properties, as shown in FIG. 14, the top of the second cart 12b. However, the light from the light source 33 reaches the light / dark sensor 32 until it passes between the light / dark sensor 32 and the light source 33.

  When the head of the second carriage 12b passes between the light and dark sensor 32 and the light source 33, the light and dark sensor 32 senses a decrease in illuminance, and the second car 12b is also detected in the same manner as the first car. A magnetic force for propelling the carriage 12 is generated. By repeating the above process a number of times equal to the number of trucks connected, a propulsive force can be applied to each truck connected.

  The acceleration / deceleration of the carriage 12 is performed by a variable resistor (not shown) between the control circuit 35 and the power source 34. The variable resistor is an element that can continuously increase or decrease the resistance value, and thereby the power supply voltage for the electromagnet 31 can be changed. Since the magnetic force of the electromagnet 31 is proportional to the voltage, the magnetic force (repulsive force) decreases as the voltage decreases and the speed of the carriage 12 decreases. On the other hand, the magnetic force (repulsive force) increases as the voltage increases. Speed increases. For this reason, although the range is limited, the speed of the carriage 12 can be controlled to some extent.

  Further, the positions of the light / dark sensor 32 and the light source 33 are not fixed, and the distance from the electromagnet 31 can be freely arranged before and after the electromagnet 31. By doing so, it is possible to drive the model railway vehicle 10 in the reverse direction.

  Similarly, the electromagnet 31 is not fixed but movable. Thus, even if the travel distance of the model train vehicle 10 increases due to the addition of straight and curved tracks, the distance between the electromagnet 31 and the light and dark sensor 32 and the light source 33 is changed or the electromagnet 31 and the light and dark sensor 32 and the light source 33 are changed. It is possible to make the model railway vehicle 10 travel stably.

  The railway model vehicle 10 configured as described above is located between the track magnet 211 and the track magnet 211 in the levitation magnet 122 disposed between the track magnet 211 and the track magnet 221. Ascending force generated by the balance between the attracting force generated between the track magnet 221 and the orbiting magnet 221 floats. Since the housing case 121 for housing the levitation magnet 122 and the levitation magnet 122 are connected by the spring 123, the housing case 121 is also levitated when the levitation magnet 122 is levitated.

  Further, the levitation magnet 122 is installed in the housing case 121 so as to be movable along a direction perpendicular to the traveling direction in which the model railway vehicle 10 travels along the rail 21 and the rail 22. Since the spring 123 connects the 121 and the levitation magnet 122 to each other, the vibration of the housing case 121 is hardly transmitted to the levitation magnet 122. This is because the vibration energy of the housing case 121 is absorbed by the spring 123. As a result, even if the housing case 121 vibrates due to an external force acting on the floating housing case 121, the attracting force generated between the flying magnet 122 and the track magnet 211, and the track magnet It becomes easy to maintain a position where the suction force generated between the rails 221 and 221 is balanced, and the model railway vehicle 10 can be stably levitated between the rails 21 and 22.

  Further, when a propulsive force for running the model railway vehicle 10 between the rail 21 and the rail 22 is applied by a magnetic force generated between the levitation magnet 122 and the electromagnet 31, this magnetic force is used as an external force. The levitation magnet 122 may vibrate by acting on the levitation magnet 122. However, since the spring 123 connects the housing case 121 and the levitation magnet 122, vibration generated by the levitation magnet 122 is difficult to be transmitted to the housing case 121. For this reason, even when the levitation magnet 122 vibrates, this vibration is suppressed from being transmitted to the housing case 121, and the model railway vehicle 10 is stably levitated between the rail 21 and the rail 22. be able to.

  In the track traveling toy 1, the railroad magnet 211 of the curved portions 21c and 21d and the track magnet 221 of the curved portions 22c and 22d are moved along the curved portions 21c, 21d, 22c and 22d. The curved portions 21c, 21d, 22c, so that the distance between the orbiting magnet 211 and the levitation magnet 122 is equal to the distance between the orbiting magnet 221 and the levitation magnet 122. 22d.

  As a result, also in the curved portions 21c, 21d, 22c, and 22d, the balance between the attractive force generated between the levitation magnet 122 and the orbital magnet 211 and the attractive force generated between the orbital magnet 221. Can be maintained. For this reason, even when the model railway vehicle 10 travels along the curved portions 21c, 21d, 22c, and 22d, the model railway vehicle 10 can be stably levitated between the rail 21 and the rail 22.

  In the embodiment described above, the track magnet 211 is the first magnet in the present invention, the rail 21 is the first rail in the present invention, the track magnet 221 is the second magnet in the present invention, and the rail 22 is the second rail in the present invention. The levitation magnet 122 is the third magnet in the present invention, the railway model vehicle 10 is the toy levitation traveling body in the present invention, and the spring 123 is the elastic member in the present invention.
